Read several places that the modifications of Shift Points on the 03-04 are coming soon. I pull a 27' 5th wheel and am very interested in adjusting the shift points and getting the tranny to hold a gear longer.
Has this modification to the Predator been completed so i can adjust the shift points?
i think diablo has the 04 stuff on the the to-do list and when it's completed it probably won't cost you 40 dollars like the SC trans options do. to the OP, the 2003 has a seperate tcm/pcm that work in combination so shift points for them probably will never happen by any tuning company. I have a 2003 and I'm thinking about switching to a 2005 pcm so I can get shift points with my DSP. Really what would help the 2003 is a idle adjust, rev limit, and speed limit functions though.
